NAME
       pwd.h - password structure
SYNOPSIS
       #include <pwd.h>
DESCRIPTION
       The  <pwd.h> header shall provide a definition for struct passwd, which
       shall include at least the following members:

              char    *pw_name   User's login name.
              uid_t    pw_uid    Numerical user ID.
              gid_t    pw_gid    Numerical group ID.
              char    *pw_dir    Initial working directory.
              char    *pw_shell  Program to use as shell.
       The  gid_t  and  uid_t  types  shall  be  defined   as   described   in
       <sys/types.h> .
       The following shall be declared as functions and may also be defined as
       macros. Function prototypes shall be provided.

              struct passwd *getpwnam(const char *);
              struct passwd *getpwuid(uid_t);
              int            getpwnam_r(const char *, struct passwd *, char *,
                                 size_t, struct passwd **);
              int            getpwuid_r(uid_t, struct passwd *, char *,
                                 size_t, struct passwd **);

              void           endpwent(void);
              struct passwd *getpwent(void);
              void           setpwent(void);
